Which strategy discovers new possibilities by exploring actions at random, often used in early learning?

Exploration by random actions is a simple way to discover what could be possible when the agent doesn’t know much yet. In reinforcement learning, you need to sample a wide range of state–action pairs to learn accurate values for what actions lead to good results. Choosing actions at random lets the agent roam freely through options, ensuring it doesn’t overlook potentially valuable actions just because they weren’t tried early on. This approach is especially important in the early learning phase when knowledge is sparse and the environment is first being explored. As learning progresses, other strategies blend exploration with exploitation, but the pure random exploration concept focuses on broad, unbiased sampling to uncover new possibilities. The decay factor typically refers to reducing a parameter over time, not a method for exploring randomly. Q-learning is the learning algorithm that updates value estimates from experience, not a dedicated exploration strategy.
